[W126 Coupe] 560 frustrations

[Axel Wulff]

Interesting.....

I'm having the crank sensor changed on my M119 engine as it was acting up 
too, and exhibiting exactly the same symptoms.

It was cutting out occasionally and I could not tell whether it was fuel or 
spark related. From what you have experienced, it might have been both.
